Applicability of Sec. 271(d)(a) & 267(s)(t) for cash payment

One of my clients has received goods from suppliers in the month of Feb on various dates for which he paid cash on daily basis. Total purchase during the month was at a cost of around Rs. 4.50 lakh (The vendor raised a single bill on last day of month) out of which he paid Rs. 1.90 lakh in cash and balance by cheque/DD. Whether sec. 271 DA or 267 ST applies in this case? 

Yes Sir, Daily limit of 10,000 not exceeded.  

Section 269ST shall not be applicable as the cash payment did not cross two lakhs or more, However, as per section 40A(3) payment or aggregate of payments made to a person in day which is exceeding 10000/- shall not be allowed as deduction.

Section 40A(3) reproduced here:

Where the assessee incurs any expenditure in respect of which a payment or aggregate of payments made to a person in a day, otherwise than by an account payee cheque drawn on a bank or account payee bank draft, ⁴⁵[or use of electronic clearing system through a bank account, exceeds ten thousand rupees,] no deduction shall be allowed in respect of such expenditure.

Therefore in the present scenario, amount paid in cash (i.e. 1.90 lakhs) shall not be allowed as expenditure while computing the PGBP income as per Income Tax Act'1961.

Kindly do let us know if any further clarification/information is required.

He purchased the goods on daily basis and paid in the form of cash in total amounting to 1.90 lakhs, therefore no penalty or dis allowance. However, please ensure payment made in day to person should not exceed the INR 10000/-.

Yup you are correct I assumed that he paid 1.90 lakhs in day.

Thanks All
